1. Work in Progress: Using Experiment-centric Learning Pedagogy to Increase Student Understanding of Chemical Principles and Concepts

   Ibirinde, T. (June 2023, American Society for Engineering Education, 2023. https://peer.asee.org/44386)

   The hands-on approach in teaching and learning is an important resource to be explored because it offers a meaningful platform for student-instructor interaction that fosters sound scientific reasoning and improves the understanding of abstract chemistry concepts. Experiment-centric pedagogy (ECP) is a contemporary teaching approach that integrates active student participation in problem-based activities through hands-on mobile devices. This paper describes how experiment-centric pedagogy (ECP) has been used to teach key chemistry concepts to undergraduate students in the chemistry discipline at Historically Black University (HBCU). To assess whether ECP achieves a lasting increase in undergraduate student curiosity and engagement in the chemistry discipline, ECP was implemented from Fall 2021 to Fall 2022 using an inexpensive, safe, and portable electronic instrumentation system usable in both classrooms and laboratories. The Motivated Strategies for Learning Questionnaire developed by Pintrich, Smith, García, and McKeachie in 1991 was used to measure the key constructs associated with students’ curiosity and engagement. The classroom observation protocol (COPUS) was used to assess instructors’ effectiveness, and signature assignments were used to evaluate knowledge gains.

2. Development and Implementation of Experiment Centric Active Learning Experiments/Activities in Transportation During the Pandemic and Beyond

   Owolabi, O.; Chavis, C.; Nwachukwu, N.; James-Okeke, P.; Ahangari, S.; Shourabi, N.; Freeman, M.; Bello, M.; Bista, K.; Gaulee, U.; et al (January 2022, Transportation Research Board 2022 Annual Meeting)

   The COVID-19 pandemic forced many colleges and universities to remain on a completely online or remote educational learning for more than a year; however, due to distraction, lack of motivation or engagement, and other internal/external pandemic contributing factors, learners could not pay attention 100% to the learning process. Additionally, given that transportation classes are very hands-on, students could not do the experiment from home due to limited resources available, thereby hampering all three phases of learner interactions. The limitation of the implementation of physical, hands-on laboratory exercises during the pandemic further exacerbated students’ actualization of the critical Accreditation Board for Engineering and Technology (ABET) outcomes in transportation: An ability to develop and conduct experiments or test hypotheses, analyze and interpret data and use scientific judgment to draw conclusions. Subsequently, this paper highlights the development and implementation of experiment centric pedagogy (ECP) home-based active learning experiments in three transportation courses: Introduction to Transportation Systems, Traffic Engineering, and Highway Engineering during the pandemic. Quantitative and qualitative student success key constructs data was collected in conjunction with the execution of classroom observation protocols that measure active learning in these transportation courses. The results reveal a significant difference between the pre, and post- tests of key constructs associated with student success, such as motivation, critical thinking, curiosity, collaboration, and metacognition. The results of the Classroom Observation Protocol for Undergraduate STEM (COPUS) show more active student engagement when ECP is implemented.

   With support from the National Science Foundation, an evidence-based experimental centric pedagogy (ECP) is being implemented across STEM disciplines at an historically black university. This is the first of its kind, where the ECP is being extended to several STEM disciplines after its successful implementation in electrical engineering to promote motivation and enhance academic achievement of minority students. One of the project objectives is to organize workshops whereby STEM faculty in biology, chemistry, physics, civil engineering, computer science, industrial engineering and transportation systems will learn how to develop and implement ECP as an active learning pedagogy. This paper highlights the strategies used for planning, publicity, implementation, and assessment of the workshop conducted in Summer 2020. Due to the ongoing pandemic, the workshop was held virtually with 360 participants registering globally. The workshop’s focus was developing and implementing inexpensive home-based hands-on learning activities. Workshop assessment revealed that participants expressed positive outcomes, 84% reported that they believe the workshop was a good use of their time and 83% said they plan to implement what they had learned at the workshop in their own practice, affording the participants more opportunities to include home-based hands-on learning in their curriculum. This project seeks not only to increase public scientific literacy, but to also contribute to the development of a diverse, globally competitive STEM workforce.

4. Preliminary Experience and Impact of Experiment-focused Teaching Approach in a Computer Architecture Course in Computer Science

   Adeniran, O. (June 2023, American Society for Engineering Education, 2023. https://sftp.asee.org/43945)

   One of the key knowledge areas in Computer Science (CS) is Digital Logic and Computer Architecture where the learning outcome is an understanding of Boolean algebra, logic gates, registers, or arithmetic logic units, etc. and explaining how software and hardware are related to a computing system. Experimental Centric based Instructional Pedagogy (ECP) with portable laboratory instrumentation might provide real hands-on experience to obtain a practical understanding of those concepts at a lower cost compared with virtual hands-on laboratories that lack direct interaction with real apparatus or no integration of labs in the course. This work presents the initial adaptation of ECP to introduce the fundamentals of digital logic concepts in a Computer Architecture course in Spring 2022 for the first time in a CS department at a university teaching such courses without a lab and serving predominantly minority students. To establish a conducive and dynamic classroom environment by discovering course content through exploration, students majoring in CS were introduced to several logic gate types, worked with breadboards to connect circuits, and carried out operations to produce the necessary output using the commercial ADALM 1K Active Learning Module. To evaluate the impact of the ECP on students; performance in the class, three different evaluation methods were used, such as classroom observation, a signature assignment, and a Motivated Strategies for Learning Questionnaire (MSLQ) survey. The Classroom Observation Protocol for Undergraduate STEM (COPUS) findings indicated greater student engagement when ECP is used; the Signature assignment results indicated improved learning outcomes for students; and the MLSQ survey, which measures students; motivation, critical thinking, curiosity, collaboration, and metacognition, determined a positive impact of the ECP on the CS participants.

5. Home-based Cantilever Beam Experiment for Civil Engineering Undergraduate Students

   Ikiriko, S. (July 2021, 2021 ASEE Virtual Annual Conference Content Access)

   null (Ed.)

   There is a growing concern in STEM fields during the ongoing pandemic about how students will be able to achieve one of the major learning outcomes; an ability to develop and conduct appropriate experimentation, analyze and interpret data, and use engineering/scientific judgement to draw conclusions. Experimental Centric Pedagogy (ECP) has been shown to promote motivation and achievement in electrical engineering among black students and students in general. This paper focuses on the development of a hands-on laboratory experiment for undergraduate students in the department of civil engineering using Mobile Hands-On Studio Technology to improve experiential learning. The home-based experiment focuses on the measurement of beam stresses resulting from weights applied to the free-end of the beam while being fixed at the other end. The beam is made up of an acrylic material and has dimensions of 1500 mm in length, 40 mm in width, and 3.175 mm in thickness. Data acquisition from strain gauges installed on the beams was made possible using ALICE Voltmeter which displays voltage readings upon beam displacement. The stress readings are then calibrated and transformed to strains based on hooke’s law relationship. Findings indicate good understanding of concepts, motivation and students learning experiences through teamwork and collaborative activities. and achievement of stated learning outcome.
